Standardization‚ therefore‚ basically involves titration‚ especially acid-base titration. Common reagents used for standardization of acids include: Pure sodium carbonate Pure borax (sodium metaborate) Pure calcium carbonate (Iceland spar) Common reagents used for standardization of alkalis comprise of solid crystalline acids like: Succinic acid Oxalic acid Good standardizing reagents should have the following characteristics: They should have a high degree of purity They should be

concentration of a protein increased with the inverse proportion of water per reagent added. MATERIALS AND METHODS Procedure and materials for Experiment #1: Protein Quantification were taken from the BIOL 1F90 Laboratory Manual #1‚ pages 1-9 (Martin‚ 2012). A change was made to the protocol for procedure 5 in Part B: Assaying Standards and Samples (page 4). In proceeding with the addition of 3 mL of Bradford Reagent to all six cuvettes‚ indicator was added to nine cuvettes instead. RESULTS

salts have no effect on the digestion of lipid and lipase will still breakdown the fat‚ because the fat in the milk itself is probably already partly emulsified‚ the rate of reaction will be the same. I drew a table‚ which showed different reagents in each tube and the time that took for the lipase to digest the lipids. The first 4 mixtures I created were controlled and were also not timed. They were used as colour standards which were maintained throughout the investigation. This was done

purpose of testing the four test tubes was to ensure that the colour change that occurred in the substance was due to a chemical change and not the substance being added to it. 3. The student saw a colour change happen because the heat causes the biuret to chemically react with the protein. The reaction should change the colour of the mixture from blue to purple in appositive test for protein. 4. Potatoes’ chips are predicted to have starch‚ lipid‚ sugar and protein in it. Potato chips main ingredients

Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines ______________________________________________ Hydrocarbons are organic compounds containing only hydrogen and carbons and further divided in major types. Hydrocarbons react differently in reagents. The basis of determining an unknown hydrocarbon is due to the differences in reactions of hydrocarbons. An unknown compound is determined using tests. The unknown gives a positive result in nitration test and gives no brown precipitate in oxidation

KEY: ABE Lab 1: Prelab: Page A17‚ Questions 1 and 2: 1. What does the term genetic disease mean? What examples of generic diseases do you know about? A genetic disease is a disease caused by an absent of defective gene in the DNA. Students may know of sickle cell anemia‚ which is a disease resulting from defective red blood cells; treatment of sickle cell anemia focuses primarily on relieving pain and controlling infections and other complications that may occur. 2.
